      *THIS PRODUCT DOES NOT FIT THE 20+ DURAMAX*

      Vehicle Fitment: 2001-2019 Duramax 6.6L

      Product Description:

       *MADE IN USA*

      Using the new MDDP filter nipple on your factory oil filter assembly, you can run the CAT 1R-1807 filter, giving you best filtration on the market utilizing the factory oil filter location. With this kit you can add a whole extra QUART to your oil capacity making it 11 quarts! Being a 10% increase in oil capaicy means a 10% longer oil service interval.

      NOTE: This will NOT FIT 2020+ L5P TRUCKS due to the smaller filter housing change. 

       THE FILTRATION ADVANTAGE

      The Cat 1R-1807 filter starts at 4 microns @ 20% efficiency and at 20 microns at 100% efficiency.  On top of filtration it has about THREE times more filtering media.  The Cat media is 2.11 times longer and the pleats are 1.13 deeper making the Cat filters area 2.39x larger than the factory ACDelco filter media.
